Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a balancer for a reciprocating piston engine improved so as to reduce the thrust load of a balancer shaft due to the oil supply to a pump side journal. SOLUTION: In a balancer for a reciprocating piston engine having a space acting by the discharge pressure of a lubricating oil pump at one end side of a balancer shaft 10R, a passage 41 for escaping pressure in the space is to be formed on one end side journal part 18RF. Consequently oil pressure acting on one end surface of the balancer shaft can be lowered, thereby lowering a thrust load acting on the balancer shaft. In particular by cutting off part of a boundary part, moving from the unexisting side of the counter weight, and e.g. forming a flat surface 40, in the rotation direction in the outer peripheral surface of the journal part of a passage for escaping pressure, the complicated process following forming the passage can be minimized and moreover the lubricating oil can be easily circulated to the increasing side of a diameter directional load due to the counter weight.
